Mckinney Hinges QCC300P Wire Harness 12 Wires 8 4 Pin

Product Description

The MCKINNEY HINGES QCC300P is a 38-inch wire harness designed for use with electrified hinge assemblies in commercial door hardware applications. This harness features 12 individual wires and terminates with both an 8-pin and a 4-pin connector, providing the electrical pathway needed to transfer low-voltage signals or power through a door frame hinge preparation. It is typically installed by licensed electricians or security systems technicians as part of an electrified door hardware retrofit or new installation. The harness ships as a single unit and weighs 0.5 pounds.

This wire harness is used in commercial access control and electrified door hardware installations where continuous power or signal transfer through a hinge point is required. Typical applications include electric latch retraction, electrified strikes, and door position monitoring circuits in office buildings, healthcare facilities, and institutional settings. The dual-connector configuration accommodates systems with split control or monitoring circuits requiring separate pin connections.

Compatibility

Designed as an OEM-style replacement wire harness for McKinney electrified hinge assemblies used in commercial door hardware applications. Verify connector pinout and harness length against existing hinge hardware before installation.

Installation Notes

Installation should be performed by a qualified electrician or credentialed low-voltage technician familiar with commercial access control systems. De-energize the door hardware circuit and verify zero voltage before handling any connectors or wire terminations. Ensure the harness is routed to avoid pinch points at the hinge pivot and that connectors are fully seated before restoring power. Consult applicable NEC requirements and the door hardware manufacturer documentation for routing and support guidelines.
